Abstract (en)

Embodiments of the invention disclosed herein are directed to articles of clothing that allow for monitoring of different analytes (e.g., electrolytes and molecules) in human sweat during fitness activity, while training, or simply in everyday life. The clothing includes a sensor system completely integrated in textile such that every sensing part is made of textile fibers. The clothing is able to control, collect, analyze, and expel the sweat over time. The textile sensor allows a spontaneous absorption of body sweat directly from the skin, while it is produced, using the hydrophilic natural properties of the textile. Then, once adsorbed, the flux of sweat is controlled and guided through the textile using a gradient of the textile's hydrophilic properties. The sweat guided through the textile(10) is analyzed through an electrochemical sensor comprising a gate fiber (22), source (16) and drain electrodes (18) connected by a conductive fiber (14) (e.g. being coated with a conductive polymer like PEDOT) woven into the textile. Finally, the sweat is collected in a reservoir and expelled for evaporation by interchanging hydrophilic and hydrophobic regions.
